In an older transmission, it might also help lengthen life too. In a new vehicle, it will make the transmission last longer. From the factory, the 700R4 and 4L60E transmissions were equipped with 4 different servo sizes based on application.

When people who have done the mod post about it, they all seem to love it and say that under normal driving, the shift feels the same, but when accelerating hard, the shift is quicker, but nothing bothersome.Īnother question is whether the Corvette Servo safe for all vehicles? Is there a mileage or age where it becomes risky? According to the hype, the answer is no.

It sounds like the perfect way to upgrade my transmission and a mod that will work with the BB tune later. It's cost is between $20-$80 depending on which kit you choose, and is a simple upgrade that can be done in the driveway in about an hour. I originally thought that the way to firm up the transmission was through a custom tune, which will be in my truck's future, but then I stumbled on the Corvette Servo.
